G Sample CSS Stylesheet for MathML (Non-Normative)

The Cascading Style Sheet sample given here is not normative. It is provided
as a guide to illustrate the sort of CSS stylesheet rules which a MathML renderer should
include in its default stylesheet in order to comply with both the CSS and MathML
specifications. In particular, there is a need to provide rules to prevent the descent of
CSS font rules into MathML expressions embedded in ambient text, and to provide support for
the mathfamily, mathslant, mathweight, mathsize,
mathcolor and mathbackground attributes.

We expect that implementation experience will allow us to provide a more authoritative
default MathML stylesheet in the future. In the interim, it is hoped that this illustrative
sample will be helpful.
